Traxxas 9T Steel 32P 3mm Shaft RC Pinion Gear - 6745

The Traxxas TRX6745 is a 9-tooth, 32-pitch steel pinion gear designed to fit motors with a 3mm shaft across a wide range of Traxxas RC vehicles. It ships with a set screw for secure shaft retention. As the smallest gear in the motor-to-drivetrain connection, the pinion gear directly affects your gearing ratio — swapping to a 9T pinion lowers the overall gear ratio, reducing top speed while increasing torque and reducing motor temperatures under load. This makes the TRX6745 a practical choice when running in demanding conditions or when fine-tuning drivetrain performance on compatible Traxxas models.

Key Features

• 9-tooth, 32-pitch (32-p) steel construction for durability under drivetrain load
• Fits 3mm motor shafts, compatible with a broad range of Traxxas brushed and brushless motors
• Includes a set screw for positive shaft engagement and secure gear retention
• Lower tooth count compared to larger pinions reduces top speed and increases low-end torque
• Direct Traxxas replacement part — style code TRX6745 for precise parts matching
